Re: McElwain/McIlwain Family Co Donegal

I am first generation American, born in Annandale NJ March 14 1934. My father, Thomas MacIlwain Campbell (1901-1972) immigrated from County Donegal about 1909. His mother was Annie (nee) MacIlwain Campbell, died in 1933, one year before my birth. She had married Tristram Wilson Campbell of County Donegal. (Our youngest son, Thomas MacIlwain Campbell II, MD, is named after my father).

I am trying to learn what relation my grandmother, Annie MacIlwain (spelling?), was to George MacIlwain, who appears to be her uncle who emigrated to London (or thereabouts) and became a famous doctor. At least there is such a famous doctor who wrote about 14 books and whose name is in the Irish Academy of Sciences.

According to some of my father's cousins who we met in Ireland in 1970, at Culmore, north of Londonderry, a certain George MacIwain, who left no sons, had left the family to become a 'famous' doctor.

I am interested in who is George MacIlwain, presumably born in County Donegal in the early 1800s and whether he is the same George MacIlwain whose name was enshrined in the Irish Academy of Sciences.
